Plants, insects and vertebrates evolved
into flowers, bees and mammalsall at
about the same time.

People appeared very recently and rapidly dominated and transformed the entire planet, also learning how to leave it. There are vast resources in our
Solar System and huge amounts of energy. Once humankind learns to capture these
resources we will become wealthy beyond our wildest dreams.

People have also created computers, and software is now being developed which can learn and evolve. If
computers ever learn how to develop other computers, they might become
completely independent of their human inventors. Independent computers might
rapidly colonize this corner of the Galaxy. But we
are so far away from even then next nearest galaxy that it is unlikely that
people or computers will ever spread very far into the Universe.

The Sun will eventually burn up the Earth, but by that time organic life will probably be largely irrelevant.
